Looks like I'm suffering from the bug that was reported years
ago, I am
running the vanilla shell that exists in Fedora 24, looks like I will have
to use an alternate Desktop Environment because I don't know why the
gnome-shell has such horrible memory management that can consume up 6GB
based on my experience, can't recall seeing it on F23 though.
How about contributing the info they need on the upstream bug (see link above) to fix this
issue? Free software can only evolve if people contribute, this includes useful
information for fixing bugs.
